UNCOUPLING DEVICE FOR CAB-COUPLINGS.

Specification of Laue" Patent.

Patented Jan. 5, 1915.

191%. Serial No. 858,696.

Original application filed April 29, 1911, Serial No. 624,178. Dividedand tliis application filed August 28,

.invented certain new and useful Improvements in Uncoupling Devices forCar-Couplers, of which the following is a specification.

This application is a division of my application filed April 29, 1911,Serial No.-

The primary object of my invention is the provision of an improved andpositive form of flexible connection wherein the use of chains, looselinks and similar devices is avoided; and with this and minor objects inview my invention consists of the parts and combination of parts as willbe hereinafter pointed out.

In the drawings Figure 1 is a top plan view of a part of a car with myimproved release rigging attached. Fig. 2 is a front elevation of thesame.

The reference numeral 1 designates the car, 2 the draw bar or couplerhead and 3 the locking pin thereof.

The pin lifting lever is composed of a relatively long arm 4 and arelatively short portion 4 having a vertically disposed dependingportion 6, said portions being at right angles to each other; the innerend of the relatively long portion passes through the eye of the lockpin, and terminates in a laterally extending hook 5. The relativelyshort portion 4 is permanently secured to the end of the car by means ofan eye bolt 7 which forms a loose pivotal connection between the saidshort arm and the car thereby accommodating the pin lifting lever to theswinging movement of the uncoupling muoperating lever.

The pin lifting lever is operated through the medium of the operatinglever 8 pivotally mounted on the bracket 9 which in turn is secured tothe end of the car, as shown, the outer portion of the lever being downwardly deflected to a plane below the under face of the car and providedwith a foot or hand member 10 preferably extended rearwardly under thecar. A portion of the lever 8 intermediate its pivot and inner end isdeflected laterallv as at 11 while its extreme inner end portion isdeflected forwardly as at 12 at right angles to the portion 8, thedeflected portions 11 and 12 underlying the relatively long portion ofthe pin lifting lever, as shown in Fig. 1, the said relatively longportion having a floating bearing on said deflected portions 11 and 12of the lever 8; so that the pin lifting lever may accommodate itself tothe vertical swinging movement of the lever 8, which moves in thevertical plane of the end of the car.

The bracket 9 is provided with a laterally extending arm 13 havingoverhanging lugs 14 and 15, the lug 15 being set at an angle to the lug14: whereby the space between these lugs is flaring.

16 is a cotter pin passing through the lugs lat and 15 and constitutes aguide for the operating lever 8.

I claim- 1. In an uncoupling device for car couplers, the combinationwith a pin lifting lever having a relatively long portion adapted toengage the pin of the coupler, and a relatively short portionterminating in an eye, said portions being at right angles to each othera device secured to the end of a car constructed to engage the eye ofthe said short portion whereby the pin lifting lever is connecteddirectly to the car, of an operating lever pivotally mounted on the endof a car for vertical movement in the plane of the end of the car, theinner end of the operating lever underlying and having a floatingbearing against said pin lifting lever.

2. In an uncoupling device for car couplers, the combination with a pinlifting lever haying a relatively long portion, and a relatively shortportion terminating in an eye, said portions being at right angles toeach other, an eye bolt secured to the end of the car to which the eyeon the short portion of the pin lever is connected to form a flexiblejoint therebetween whereby the said pin is directly connected to the endof the car, of an operating lever 'pivotally mounted on the end of thecar for vertical movement in the plane of the end of the car andconstructed to engage and operate said pin lever.

3. In an uncoupling device for car couplers, the combination with a pinlifting lever having a relatively long portion, and

a relatively short portion terminating in an eye,- an eye bolt securedto the end of the car to which the eye on the short portion ofthe pinlever is connected to form a flexi- 5 ble joint therebetween whereby thesaid lever isdirectly connected to the end of the car, of an operatinglever pivotally mounted on the end. of the car for vertical movement inthe-plane of the end of the car and constructed to engage said pinlever,

. said operating rod having a laterally bent portion intermediate itspivot and its inner" end and an inner end portion bent at right
